Another thing we should document somewhere is that 5.0 won't cycle out your 4.x kernels, because 5.0 keeps them in a different place, only cycling out 5.0 kernels. Once the upgrade is complete and you know you're not backing out, removing the old 4.x modules and kernel directorie (and any .old) can be used to recover a lot of space. If the user foolishly has /tmp on a small /, they'll want to symlink it to /var/tmp, /usr/tmp, or the like during the install, to avoid having the install.xxxxx backup files on /. In order to useful upgrade on box, I have to move the old kernel to /usr, and in the event I'm backing out, point the loader at it manually.
